Curvature properties of projective semi-symmetric linear connections
Milan Lj. Zlatanović; Miloš Z. Petrović; Miroslav D. Maksimović;Abstract
We study a projective semi-symmetric linear connection on a differentiable manifold $\mathcal{M}$ endowed with a Riemannian metric $g$. We start with linearly independent curvature tensors $\underset\theta R$, $\theta=0,1,\ldots,5$
and derive the tensors $\underset\theta W$ for $\theta=0,1,\ldots,5$ that, as we show, coincide with the Weyl tensor of projective curvature $W{}^g$. This confirms the well-known fact that there does not exist a generalization of the Weyl projective curvature tensor $W{}^g$.
